An axial setting device in a housing, especially for actuating a multi-plate coupling whose friction plates are alternately connected in a rotationally fast and axially displaceable way to the one and the other respectively of two parts rotatable relative to one another, which rest against an axially fixed supporting disc and which can be loaded by an axially displaceable pressure disc, comprising a setting disc which is rotatably supported in the housing, which is mounted so as to be axially fixed in the housing and which is rotatingly drivable, a pressure disc which is held in the housing, which is held in a rotationally fast way by anti-rotation means arranged in the housing and which is axially displaceable in the housing, ball groove configurations in the surfaces of the setting disc and of the pressure disc, which surfaces face one another, which ball groove configurations extend in the circumferential direction, have oppositely directed gradients across the circumference and are associated with one another in pairs, so as to jointly accommodate a ball, and rotary driving means for the setting disc mounted in the housing, wherein the anti-rotation means are designed so as to be releasable from the pressure disc.
