A torque reaction mechanism comprising a coupling arrangement (170) operable between an apparatus (10) having a rotary drive input (120) such as a drive socket, and a powered driving tool (160) for delivering rotational torque to the rotary drive input (120). The coupling arrangement (170) acts to transfer reaction torque away from the operator of the powered driving tool (160). The coupling arrangement (170) comprises a first (fixed) coupling element (171) disposed around the rotary drive input (120), and a second (corresponding) coupling element (172) on the powered driving tool 160. The arrangement is such that cooperation between the two coupling elements (171, 172) is adapted to allow displacement therebetween in the direction corresponding to the axis of rotation of the driving tool (160) while constraining the two coupling elements against relative rotation about the axis of rotation. With this arrangement, reaction torque arising from operation of the powered driving tool (160) is transferred through the coupling element (172) on the tool (160) to the respective fixed coupling element (171). In this way, an operator holding the powered driving tool (160) merely has to guide the tool during its operation and does not have to counteract any reaction torque. The first coupling element (171) is configured as a sleeve (175) disposed around the rotary drive input (120). The second coupling element 172 is configured as a block (177) which is rigidly mounted on the body (163) of the driving tool (160) and which is adapted to be received in the sleeve (175) for sliding movement therealong.

An operating mechanism (40) for a valve (11) having a valve body (13) defining a valve seat (19) and a valve member (21) moveable into and out of engagement with the valve seat (19). The valve member (21) comprises a valve disc (25), a valve stem (23), and a bush (29) through which the valve stem (23) extends in threaded engagement therewith whereby relative rotation between the bush (29) and the valve stem (23) causes axial displacement of the valve stem (23) relative to the bush (29). The operating mechanism (40) comprises two operating drive sockets (104, 106) in opposed relation, each of which is drivingly connected to the bush (29). The operating mechanism (40) also comprises two unlocking drive sockets (118, 120) in opposed relation, each of which is drivingly connected to the bush (29). The drive ratio between the operating drive sockets (104, 106) and the bush (29), and the drive ratio between the unlocking drive sockets (118, 120) and the bush (29) are different from each other such that a larger torque is delivered to the bush (29) from operation of either one of the unlocking drive sockets (118, 120) in comparison to the torque delivered to the bush (29) from operation of the either one of the operating drive sockets (104, 106) for the same torque input. With this arrangement, either one of the unlocking drive sockets (118, 120) can be used for unlocking the valve; that is, to move the valve member (21) into a 'just open' or throttled position in which the valve disc (25) is out of sealing engagement with the valve seat (19) without rotation of the valve stem (23). Further, either one of the operating drive sockets (104, 106) can be used for opening and closing the valve (11), as well as valve locking. Because there are two operating drive sockets (104, 106) in opposed relation, and also two unlocking drive sockets (118, 120) also in opposed relation, an operator can access the operating mechanism (40) from either side thereof according to what is more convenient.
