A fluid flow transfer system 200 for transferring a fluid flow from a stationary member 202 to an adjacent rotatable member 204 is provided. The system 200 includes one or more fluid supply conduits 214 and a gearbox flow path 222 configured to channel the flow of fluid through the power gearbox 216. The system 200 also includes a transfer sleeve device 224 configured to receive the flow of fluid from the gearbox flow path 222. The transfer sleeve device 224 includes a stationary transfer sleeve member 202 and a rotatable transfer sleeve member 204. The transfer sleeve device 222 is configured to transfer the flow of fluid between the stationary transfer sleeve member 202 and the rotatable transfer sleeve member 204. A pitch change mechanism (PCM) actuator 230 is configured to receive the flow of fluid through one or more of a plurality of flow ports 228 wherein the plurality of flow ports 228 direct the flow of fluid to a respective actuator 230.
