The device has a drive element (1) connected to the drive unit, a take-off element (5) connected to a tool holder (9), and a coupling element (11) with two ends (12,13) connected to drive and take-off elements. The central section of the coupling carries, resp. is formed as, a spring plate coupling. Drive and take-off elements are positioned to be always coaxial. At least one end of the coupling elements is polygonal. The tool is a screw driver bit, or a drill/cutting tool. The axial space between two neighboring spring plates of the coupling element is filled with injected plastic, esp. elastomer. |
