The present invention relates to an actuation device for a clutch comprising a stator device, a rotor device which can be rotated relative to the stator device, and a carriage device which can be displaced in a limited manner in axial direction relative to the rotor device, a rolling body threaded drive comprising at least three windings and a substantially annular rolling body circuit with rolling bodies being provided between the rotor device and the carriage device, the substantially annular rolling body circuit having a lane change region that is designed such that rolling bodies run between a first and a second winding in circumferential direction before the lane change region, and rolling bodies run between the second and a third winding in circumferential direction after the lane change region, the substantially annular rolling body circuit being formed from at least two components.
