The invention relates to an inductive torsion bar torque sensor (100), comprising at least a first and a second stator arrangement (10,10A) with each a receiving structure (11,11A) comprising a periodically repeated structure having a first and a second period, a first and a second rotor (20,20 A) rotatably arranged with respect to the first and second stator arrangements (10,10 A) forming two inductive position sensors (1,11A) for measuring an angle at each end of a torsion bar (5) and generate respective signals, at least one excitation or transmitter coil (40) and an oscillator circuit for generating a periodic alternating voltage and coupling it into the excitation coil(s) (40). The periodicity of the first receiving structure (11) is different from the periodicity of the second receiving structure (11A), the first and second receiving structures (11,11A) comprising a first and a second coil structure (101,101;102,102), the first rotatable rotor (20) serving the purpose of influencing the strength of an inductive coupling between the excitation coil(s) (40) and the first receiving structure (11), the second rotatable rotor (20A) serving the purpose of influencing the strength of an inductive coupling between the/an excitation coil(s) (40) and the second receiving 15 structure (11A). The signals generated by the first and second pair of receiving structures (11,11A) and rotors (20,20A) are orthogonal.
