A friction torque device includes an adjustment mechanism for adjusting the device in response to wear on a friction surface within the device, and an adjustment limiting member for controlling adjustment thereof. In one embodiment, the adjustment mechanism includes a first cam ring rotatable relative to both a pressure plate and a cover, and a second cam ring engaging the first cam ring on a side of the first cam ring opposite the cover and rotatably fixed relative to the cover. The first cam ring is rotatable with respect to the second cam ring such that ramped surfaces cam against each other to increase the axial displacement of the first and second cam rings, whereby the axial displacement compensates for wear on the friction surface. The adjustment limiting device is selectively engagable with the first cam ring to inhibit rotation thereof.
