Abstract: A flexible coupling includes a flexible torque disc comprising a plurality of mount points and a first coupling member mounted to a first subset of said mount points. The coupling also includes one or more second coupling members each mounted to a second subset of said mount points. The first coupling member comprises one or more flanges substantially parallel with said torque disc and the one or more second coupling members each has a groove engaging with said one or more flanges so as to limit the displacement of said first coupling member with respect to said second coupling member.

Abstract: A flexible coupling comprising: a flexible torque disc comprising a plurality of mount points; a first coupling member mounted to a first subset of said mount points; one or more second coupling members each mounted to a second subset of said mount points; wherein said first coupling member comprises one or more flanges substantially parallel with said torque disc; and wherein said one or more second coupling members each has a groove engaging with said one or more flanges so as to limit the displacement of said first coupling member with respect to said second coupling member. This coupling arrangement is easy to assemble, repair and maintain in confined spaces, while also being lightweight and using a small number of components.
