Abstract: A hollow shaft coupling for connecting a shaft to a hollow shaft, where the hollow shaft coupling can be arranged completely in the hollow shaft and can effect clamping both radially inwardly as well as radially outwardly. The coupling enables a first clamping unit to clamp the hollow shaft coupling radially inwardly against the shaft and a second clamping unit which is separate from the first clamping unit to clamp the hollow shaft coupling radially outwardly against the inner circumferential surface of the hollow shaft, with the two clamping units spaced apart from one another axially, and the two clamping units connected to one another via a play-free and rotationally stable coupling which is arranged between them.

Abstract: A hollow shaft coupling for connecting a shaft (3) to a hollow shaft (2), wherein the hollow shaft coupling (1) can be arranged completely in the hollow shaft (2) and can effect clamping both axially inwardly as well as axially outwardly. The coupling (1) enables a first clamping unit (5) to clamp the hollow shaft coupling (1) axially inwardly against the shaft (3) and a second clamping unit (6) which is separate from the first clamping unit (5) to clamp the hollow shaft coupling (1) axially outwardly against the inner circumferential surface (7) of the hollow shaft (3), with the two clamping units (5, 6) spaced apart from one another axially, and the two clamping units (5, 6) connected to one another via a play-free and rotationally stable coupling which is arranged between them.

Abstract: Proposed is a closing device (1) for applying screw tops to containers, in particular beverage bottles, comprising a coupling (5) which transmits a torque from a drive unit to a screw top, the drive unit comprising a drive rotor and an output rotor as well as a torque-transmitting device having at least one magnet and a hysteresis material which interacts with same, or at least one additional magnet. The closing device (1) is characterized by at least one sensor (9) which detects the relative position between the drive rotor (21) and the output rotor (23).
