A device to control rotation is disclosed. The device includes a stationary portion having an internal aperture with a frustoconical inner surface. The device also includes a movable portion having a frustoconical outer surface, adapted to engage the frustoconical inner surface, to stop rotation between the movable portion and the stationary portion when engaged. An input sleeve is included, configured to transmit an applied rotational force to the device, also configured so that, as the input sleeve moves in a first axial direction, the moveable portion engages the stationary portion, and as the input sleeve moves in a second and opposite axial direction, the moveable portion is pushed out of engagement with the stationary portion. The device further includes a one-way rotation governor, non-rotatably attached to the movable portion and non-rotatably attached to a shaft and configured to allow rotation between the movable portion and the shaft in one rotational direction and prevent rotation between the movable portion and the shaft in a second opposite rotational direction.
