Overall view of the engine's accessory drive adapter, located on the turbopump gearbox.

The accessory drive adapter consists of two counter-rotating gears, powered by the turbopump gearbox. The main hydraulic pump (used power the gimbal actuators) connects to the left-hand adapter (I was unable to determine what attached to the other adapter).
