Coupling device, in particular for industrial applications

Coupling device, in particular for industrial applications, for the torque-transmitting connection of two shaft segments, comprising:

• a first coupling part for coupling to a first shaft segment,
• a second coupling part for coupling to a second shaft segment,
• wherein the first coupling part has a plurality of coupling projections arranged at regular angular intervals about a centre axis of the first coupling part,
• wherein the second coupling part has a corresponding plurality of coupling projections arranged at regular angular intervals about a centre axis of the second coupling part,
• wherein at least two adjacent coupling projections of the first and second coupling parts are each connected in a force-transmitting manner by means of an elastic connection arrangement,
• wherein the elastic connection arrangement has two connecting links which are angled relative to one another and which extend between the adjacent coupling projections, wherein the connecting links at mutually facing areas are coupled in a force-transmitting manner to at least one tension strand portion which extends substantially in the radial direction, and
• where the coupling device further comprises an intermediate coupling part which is situated between the first and the second coupling part and which has a central axis of rotation, the connecting links at mutually facing areas being coupled to the intermediate coupling part in a force-transmitting manner via the at least one tension strand portion which extends in the radial direction, wherein the intermediate coupling part is freely movable relative to the first and second coupling parts.
