A flexible coupling includes a flexure, a first drive member defining an axis and connected to the flexure, and a second drive member. The second drive member defines an axis and is connected to the flexure on a side of the flexure opposite the first drive member. An angular stop is fixed within the first drive member, extends through a portion of the second drive member, and is arranged to limit angular misalignment of the first drive member axis relative to the second drive member axis while transmitting torque between the first and second drive members.
