A B S T R A C T In the case of an apparatus for adjusting the relative rotational position between a gear-wheel and a ring-gear mounted equiaxially therewith, more particularly on the rotating drum of a sheet-fed rotary press, coupling elements are provided which provide a non-positive coupling between the said gear-wheel and ring-gear by means or a spring-force. An axially mobile adjust- ing element, provided with a thread, is in operative connection, through a plurality of radially arranged pressure-levers, with the said coupling elements, in such a manner that, for the pur- pose of releasing the non-positive coupling, the spring-force acting upon the coupling elements is reduced. The adjusting element is coupled to a switch in such a manner that, when the said coupling is released, the power- supply to the drive is cut off before the coupling force is reduced to a value below that needed for the drive.
