Abstract
A coupling device facilitates coupling of an ink transfer roller in an inking unit or printing unit of a printing machine. The ink transfer roller includes at least a roller body to which an end pin is connected, with each end pin of the roller being mounted to rotate in a bearing housing of the inking unit or printing unit via at least one bearing. The end pins of the roller include couplings with which the roller can be coupled and fastened in the inking unit or printing unit, with at least one end pin of the roller being splined to a shaft piece of a drive. The coupling device includes an actuator, with which at least one end pin of the ink transfer roller can be positioned against the shaft piece of the drive.
