ABSTRACT:
An apparatus with an initiator for detecting the rotational position of a shaft (10) comprising a housing (2) containing an electric sensor element (14) and a movable revolving body (22) fastened on the shaft (10). The apparatus achieves a simple and functionally reliable alignment of the revolving body (22) with respect to the sensor element (14) in order to facilitate assembly or adjustment at low cost. The revolving body (22) is rotationally fixed to the shaft (10) by means of a clamping connection and is adjustable in the circumferential and/or axial direction upon contact with a stop body in the housing once the clamping force of the clamping connection has been overcome.
