Abstract
A device for attaching screw caps to containers has a screwing head driven by an electric motor. To avoid a high peak torque in tightening screw caps, the screwing head is coupled with the drive motor via a soft torsion coupling, which absorbs the energy of the masses that continue to rotate. The torsion coupling is embodied as a tube of a resilient elastomer. The screw cap is prevented from loosening as the masses revolve backward by means of a reverse movement stop which is associated with the screwing head.
