The present invention is directed to a flexible coupling device adapted to connect a first rotatable shaft with a second rotatable shaft. The coupling device generally includes a pair of opposing hubs, each of which is adapted to be secured to a respective shaft. A connecting sleeve made from an elastomeric material extends between and engages each of the hubs. According to the present invention, the connecting sleeve also contains a rigid member defining at least one failsafe element or rigid engaging element that prevents the hubs from disengaging the connecting sleeve should the elastomeric material begin to wear and fail.
