Abstract
A flexible coupling is provided for connecting ends of two shafts which may be misaligned. The coupling includes a first member which is attached to one of the shafts and a second member which is attached to the other shaft. Each of the members has three dogs extending toward the other member but spaced therefrom with a resilient drive insert located therebetween. The drive insert has an annular flange which extends around the dogs and between the members and specifically engages shoulders or recesses on both members. The dogs have negative angles so that in the event one of the members should become loose on its shaft, the dogs will still remain in engagement. Finally, hubs of the members have locking inserts which enable the hubs to accommodate different shaft shapes.
