Abstract

The machine pressure medium-operated tool can be replaced using a quick-release coupling system (1) comprising a mechanical coupling and at least one fluid coupling (3). The fluid coupling has a machine-side coupling component (31) and a tool-side coupling (32). When the mechanical couplings are engaged, they are positioned at a predetermined distance from one another. At least one of the coupling components can be moved by a motorised drive in the direction of the other to close the coupling and at least one of the coupling components is deformable or adjustable in position to compensate for alignment errors.
