Some embodiments are directed to an apparatus for managing fluid flow in a vehicle, that includes an epicyclic gear set having first, and second inputs configured to receive rotational drive input from a torque output feature of a powertrain and a rotary actuator respectively. A pump driver is provided for driving a fluid pump, the pump driver being configured to receive rotational drive input from an output of the epicyclic gear set. A controller is configured to determine information corresponding to the rotational speed of the torque output feature using information generated by a rotational speed sensor and based on this control the rotary actuator, such that the pump driver is caused to rotate at substantially a pre-specified speed.
