Claim Text:
1. A steering torque-steering angle sensor comprising a steering torque sensor module and a steering angle sensor module, wherein the steering torque sensor module comprises a first magnetic encoder and at least one first magnetic field sensor element, wherein the steering angle sensor module comprises at least one second magnetic field sensor element and a third sensor element, wherein the second magnetic field sensor element senses the magnetic field of the first magnetic encoder of the steering torque sensor module, wherein the third sensor element senses a magnetic field generated by a second encoder, wherein the steering angle sensor module has a defined angle of rotation measurement range of more than 360°, and wherein the first and second magnetic encoders are designed in respect of their numbers of poles such that the second magnetic field sensor element associated with the first magnetic encoder in relation to angle recording detects n poles or pairs of poles over an entire angle of rotation measurement range of the angle sensor arrangement and the third magnetic field sensor element associated with the second magnetic encoder detects n−1+Δ poles or pairs of poles over the entire angle of rotation measurement range of the angle sensor arrangement, wherein Δ is defined as a real number between 0 and 1 and n is defined as a natural number.
