  We investigate the thermodynamics of a hybrid quantum device consisting of
two qubits collectively interacting with a quantum rotor and coupled
dissipatively to two equilibrium reservoirs at different temperatures. By
modelling the dynamics and the resulting steady state of the system using a
collision model, we identify the functioning of the device as a thermal engine,
a refrigerator or an accelerator. In addition, we also look into the device's
capacity to operate as a heat rectifier, and optimise both the rectification
coefficient and the heat flow simultaneously. Drawing an analogy to heat
rectification and since we are interested in the conversion of energy into the
rotor's kinetic energy, we introduce the concept of angular momentum
rectification which may be employed to control work extraction through an
external load.
