An internally assisted friction clutch having both engagement springs and assister springs extending between a cover and a release sleeve is disclosed. The radially directed forces exerted by the springs continually center and rotatably drive the release sleeve co-axially relative to the cover under normal operating conditions. In order to prevent excessive relative rotation, a plurality of protrusions are formed on the release sleeve which extend into respective recesses formed on the cover. The recesses are sized to be significantly larger than the protrusions so as to cause engagement only when four to five degrees of relative rotational movement or more occurs between the release sleeve and the cover.
