The motor-actuable coupler is used for connecting workpiece grippers with a manipulating device, in particular a robot, which passes on workpieces from one stamping press to the next. The coupler consists of a fixed element (12, 66, 80, 38) on the drive side and a connecting element (10, 54) on the gripper side. Since normally a very large number of different workpiece grippers are employed and the connecting elements on the gripper side entail great costs, it is proposed that the fixed element of the coupler has a collet chuck (66, 74, 80, 38), and that the connecting element (10, 54) is a tube section, which can be centered in the fixed element (12, 66, 80) spaced apart from the clamping area (at 68, 76) located at the front end of the collet chuck. The tube section (10) is preferably centered by clamping faces (70, 78) and/or by cone surfaces (58) at its end which can be inserted into the collet chuck (14).
