Abstract: A transfer coupling includes a static component and a rotatable component arranged concentrically, the static component including a first number of radially extending ports and the rotatable component having a second number of radially extending ports the radially extending ports arranged in a common circumferential plane wherein the ports are configured and arranged, in use, to homogenise a flow area for a fluid being transferred through the ports and thereby create a homogenous volume flow.

Abstract: A drive shaft component, which can be connected or is connected to the input side of a gear box in a gas turbine engine, in particular an aircraft engine, characterized in that the drive shaft component has partially a region including fiber reinforced plastic, the fibers in this region being arranged only in an angular range of +/?40° to 50°, in particular of +/?42° to 48°, most particularly +/?45°, in relation to the main axis of rotation of the drive shaft component. The invention also concerns a method for producing a drive shaft component and a gas turbine engine.
