Gas turbine engine generator system with torsional damping coupling

The present application and the resultant patent provide a gas turbine engine generator system (100). The gas turbine engine generator system (100) may include a turbine (130), a generator (150), and a shaft (140). The turbine (130) drives the generator (150) via the shaft (140). A torsional damping coupling (160) may be positioned about the shaft (140) so as to limit the transmission of torque to the turbine (130) during a generator based fault event.
