An assembly for an electric machine may include a rotor shaft and a temperature sensor. The rotor shaft may rotate about an axial rotation axis and/or the rotor shaft may include a wall extending in a circumferential direction and axially. In an interior of the rotor shaft, the wall may radially delimit a hollow space. The temperature sensor may be attached radially inside the wall. The rotor shaft may further include a first axial end face, a second axial end face located opposite the first axial end face, an inlet opening for admitting a cooling fluid into the hollow space, and at least one outlet opening for discharging the cooling fluid out of the hollow space. The cooling fluid may flow along the temperature sensor.
