ABSTRACT:
A coupling device for transmitting torque from a first film transporting rack to a neighboring second film transporting rack in a developing machine has a first shaft extending outwardly from a sidewall of one of the racks, a second shaft which extends outwardly from one sidewall of the other rack and is movable into axial alignment with the first shaft, first and second gears on the respective shafts, and a sleeve having an internal gear which is in permanent mesh with one of the gears and is movable axially into and from mesh with the other gear. The sleeve has internal elastic prongs which extend into a circumferential groove of the shaft for the one gear when the internal gear meshes with the other gear.
