ABSTRACT:
A self-coupling flange for coupling and at the same time both axially and radially locking two components especially is suited for coupling of an actuator to a valve. The flange includes an upper member to be fixed to or incorporated into one component and a lower part member to be fixed to another component. An annular piston having a locking ring is movable into an inner axial opening in the lower member to move the two members from an offset position to an aligned position with respective sloping contact faces in abutment.
