Abstract

The invention relates to a torsionally rigid, play-free, metal bellows-type, flexible shaft coupling for the torque-transmissive interconnection of two shafts. A metal bellows (1) has its generally axially flanged-out ends (1′) clamped on the ends of shafts (4) for frictional engagement. For the provision of a torsionally rigid, torsionally play-free and flexible coupling which can be manufactured inexpensively, which is readily available due to a modular design and which does not affect the drive train dynamics, the ends (1′) of metal bellows (1) have clamping rings (2, 2a) placed thereon which have slots (2′) therein and are adapted to be compressed by the width of slot (2′) to preferably directly clamp the ends (1′) of metal bellows (2) down on shafts (4).
