A device adapted to control rotation of a driven member (26) relative to rotation of a driving member (14) includes an eccentric sleeve (42) positioned radially outwardly from the driven member (26). The eccentric sleeve (42) is rotatable relative to the driven member (26). The device also includes a gear sleeve (50,54) positioned between the eccentric sleeve (42) and the driving member (14). The gear sleeve (50,54) is rotatable relative to the eccentric sleeve (42) and drivably coupled to the driven member (26). The device further includes a control member (80) operable to control the rotation of the eccentric sleeve (42), thereby controlling rotation of the gear sleeve (50,54) and the driven member (26) relative to the driving member (14). |
