In one example embodiment, a fluid transfer coupling arrangement includes a hollow shaft, 50, that is arranged in a housing, 40, and rotatable about an axis. The hollow shaft is provided by a wall, 58, having radially spaced interior, 60, and exterior surfaces, 62. A first passage extends through the wall and is configured to communicate fluid between the interior and exterior surfaces. A fluid coupling is located mid-shaft, sealed about the exterior surface, and aligns to the first passage. The fluid coupling provides a second passage that is in fluid communication with the first passage. The fluid coupling includes a locating feature configured to permit radial movement of the fluid coupling, 46, relative to the housing, 40, and allowing the fluid coupling to track subtle shaft movements. |
