The invention relates to a device for fixing and rotationally driving a gripper tool or the like on the arm of a crane, an excavator or a similar transporting and lifting machine, said device comprising a housing (1). An adapter plate (5) comprising an annular flange (6) is arranged on the housing, said flange being rotatable about the housing (1) by means of a grooved ball bearing (8). Said housing (1) comprises a hydromotor (12) which transmits the rotational movement thereof to the adapter plate (5) by means of an output flange (13). The output flange (13) and the adapter plate (5) are axially distanced (14) from each other. Screw bolts (15) produce the rotary driving force between the output flange (13) and the adapter plate (5).
