Zusammenfassung:The tool i.e. drilling hammer (1), has a driven shaft (22) coupled with a tool receiver (2). A motor (5) is coupled with a drive shaft (21). A rotational torque-controlled coupler (20) comprises spring elements (26) i.e. spiral springs, for connecting the drive- and driven shafts with each other in a force-fit manner. The elements are inseparably suspended at eccentric cams of the drive- and driven shafts, where rotating movements of ends of the elements and the shafts are synchronous with each other. The driven shaft is provided coaxial to the drive shaft. An independent claim is also included for a method for operating a hand-held power tool.
