A torque sensor unit includes a ring magnet that is connectable to a first partial shaft in a torque-proof manner, a magnetic yoke that is connectable to a second partial shaft and that is arranged in a magnetic field of the ring magnet, magnetic flux conductors that are connectable to the second partial shaft and that conduct magnetic fluxes generated by the magnetic yoke, a sensor unit having a first housing, which detects a change in rotational angle between the partial shafts by measuring magnetic flux density generated between the magnetic flux conductors, and a second housing that surrounds the ring magnet, the magnetic yoke, the magnetic flux conductors, and the sensor unit. The second housing may include a housing opening that is at least partly closed by a housing cover. The second housing and the housing cover may comprise magnetically conductive material for magnetically shielding the torque sensor unit.
