1. A device for a track- or rail-mounted closure drive assembly configured to be driven by a motor, the device comprising:
a lever and cam arrangement including a lever, the lever and cam arrangement configured to drive an engagement member between an engaged position and a disengaged position, the engaged position allowing drive of a closure by the motor, the disengaged position disconnecting the motor from the closure; and
a rotating body separate from the lever, the lever being able to rotate with respect to the rotating body, the rotating body including one or more camming surfaces and one or more peripheral surfaces;
wherein:
operation of the lever is configured to cause rotation of the rotating body by way of the one or more camming surfaces,
rotation of the rotating body is configured to drive movement of the engagement member by way of the one or more camming surfaces, and
the peripheral surfaces include visual indicia to indicate to a user an orientation of the one or more camming surfaces and hence whether the engagement member is in the engaged position or the disengaged position.
