1. A clutch device comprising:
at least one counter-pressure plate;
a contact plate movable relative to the counter-pressure plate to a limited extent in an axial direction of the clutch device to frictionally clamp a clutch plate between the counter-pressure plate and the contact plate; and
a wear adjuster to compensate for wearing of the clutch plate, where the wear adjuster has at least one drive ring rotatable and clampable in the axial direction and at least one ramp ring rotatable and clampable in the axial direction, the ramp ring connected to the drive ring via a torque-transferring link permitting limited relative travel in two circumferential directions of the clutch device, where a rigidity of the link is different when moved in a first of the two circumferential directions than when moved in a second of the two circumferential directions, the link deforming in the axial direction during clamping of the clutch plate between the counter-pressure plate and the contact plate.
