A device and a method of aligning a full or partial turn absolute rotary position encoder (310) with a predetermined desired rotary position of an axle (302). A trigger (335) is generated when the axle is in a predetermined triggering rotary position. The trigger initiates acquiring a position signal (315) from the absolute rotary position encoder (310). This acquired position signal is a base for determining a correction factor (355). The correction factor is then used to transform subsequent position signals (315) from the absolute rotary position encoder (310) into aligned position signals (365). The aligned position signals are equivalent to position signals the absolute rotary position encoder (310) would have generated had the absolute rotary position encoder been physically aligned with the predetermined desired rotational position on the motor axle (302).
