A power steering apparatus assists steering of a vehicle by conferring torque generated by an electric motor to a steering mechanism. The apparatus includes a steering column with linked upper and lower steering shafts. An angle sensor (AS) includes a gear and magnet to measure the steering shaft angle. A torque sensor (TS) measures the relative shift angle between the upper and lower steering shaft and includes a multi-pole ring magnet and a magnetic flux conductor. The TS and AS are arranged such that the AS magnet influences the TS measurement creating a steering shaft angle depending error signal. The steering mechanism is arranged such that a zero crossing of an envelope curve of the error signal is given for the neutral position of the steering apparatus or a range of the steering position in which the steering angle is less than a threshold angle limit.
