Abstract
An apparatus for axially aligning a first coupling member and a second coupling member that can be connected so as to form a rotating assembly. The apparatus includes a measurement arrangement configured to be mounted onto the first coupling member and to be rotated therewith. The measurement arrangement includes an emitter arrangement configured to emit first and second signals in the direction of the second coupling member so as to cause at least a portion of said first and second signals to be reflected by the second coupling member. The measurement apparatus further has a capture arrangement configured to capture at least a portion of the first and second reflected signals. The apparatus includes a control arrangement configured to determine an offset in axial alignment between the first and second coupling member based on at least the first and second reflected signals.
