A generator coupling assembly includes an output housing, an output member rotationally supported by the output housing, a generator powered by the output member, and a clutch adapter. The generator includes a generator stator, a generator rotor rotatably supported within the generator stator, a shaft coupled to the generator rotor, and a clutch member arranged on the shaft. The clutch adapter is coupled to and radially retained by the output member, and includes a clutching structure configured for selective engagement with the clutch member to engage the clutch member and the clutch adapter for co-rotation.

1. A generator coupling assembly comprising: an output housing;an output member rotatably supported by the output housing;a generator powered by the output member, the generator comprising: a generator stator;a generator rotor rotatably supported within the generator stator;a shaft coupled to the generator rotor for co-rotation therewith; anda clutch member arranged on the shaft; anda clutch adapter coupled to the output member with a splined connection for co-rotation therewith, wherein the clutch adapter includes a clutching structure configured for selective engagement with the clutch member to engage the clutch member and the clutch adapter for co-rotation, and wherein the clutch adapter is radially retained by the output member. 2. The assembly of claim 1, wherein the shaft is configured to axially translate to selectively engage the clutch member and the clutch adapter. 3. The assembly of claim 1, wherein the clutch member comprises a first toothed clutch face located at a first end of the shaft, and wherein the clutching structure of the clutch adapter comprises a second toothed clutch face. 4. The assembly of claim 3, wherein the first toothed clutch face is integrally formed with the shaft. 5. The assembly of claim 1, the shaft further comprising: a shear section configured to facilitate shaft failure under excessive torque conditions to disengage the generator. 6. The assembly of claim 5 and further comprising: a support member extending from the clutch adapter into a hollow region of the shaft at or near the shear section to radially retain a portion of the shaft upon shaft failure. 7. The assembly of claim 1, wherein the output housing comprises a gearbox housing, and wherein the output member comprises a gearbox power shaft. 8. The assembly of claim 1 and further comprising: a seal member configured to create a fluid seal between the output housing and the output member. 9. The assembly of claim 1 and further comprising: a seal member configured to create a fluid seal between the output housing and the output member, wherein the seal member maintains a fluid seal between the output housing and the output member when the generator and the clutch adapter are uninstalled from the output member. 10. The assembly of claim 1, wherein the generator further comprises a generator housing, the assembly further comprising: a seal member configured to create a fluid seal between the output housing and the generator housing. 11. A generator system comprising: a prime mover for providing a rotational force;a gearbox comprising: a gearbox housing; andan output member rotationally supported by the gearbox housing for transmitting rotational force from the prime mover;a generator powered by the output member, the generator comprising: a generator housing;a generator stator;a generator rotor rotatably supported within the generator stator;a shaft coupled to the generator rotor for co-rotation therewith; anda clutch member arranged on the shaft; anda clutch adapter coupled to the output member of the gearbox with a splined connection for co-rotation therewith, wherein the clutch adapter includes a clutching structure configured for selective engagement with the clutch member to engage the clutch member and the clutch adapter for co-rotation, and wherein the clutch adapter is radially retained by the output member. 12. The system of claim 11, wherein the prime mover comprises a gas turbine engine. 13. The system of claim 11, wherein the shaft is configured to axially translate to selectively engage the clutch member and the clutch adapter. 14. The system of claim 11, wherein the clutch member comprises a first toothed clutch face located at a first end of the shaft, and wherein the clutching structure of the clutch adapter comprises a second toothed clutch face. 15. The system of claim 11, the shaft further comprising: a shear section configured to facilitate shaft failure under excessive torque conditions to disengage the generator; anda support member extending from the clutch adapter into a hollow region of the shaft at or near the shear section to radially retain a portion of the shaft upon shaft failure. 16. The system of claim 11 and further comprising: a seal member configured to create a fluid seal between the gearbox housing and the output member. 17. The system of claim 11 and further comprising: a seal member configured to create a fluid seal between the output housing and the output member, wherein the seal member maintains a fluid seal between the output housing and the output member when the generator and the clutch adapter are uninstalled from the output member. 18. The system of claim 11, wherein the generator further comprises a generator housing, the assembly further comprising: a seal member configured to create a fluid seal between the output housing and the generator housing.
