A steering assistance actuator for a vehicle includes a actuator shaft, a torque sensor, a motor, a drive mechanism and a drive housing. The actuator shaft is rotatable about a first axis. The actuator shaft includes an integral torque sensor. The motor has an output shaft rotatable about a second axis. The second axis is substantially parallel to the first axis. The drive mechanism is disposed between and drivingly connects the motor and the steering column. The drive mechanism provides a speed reduction from the motor to the actuator shaft. The drive housing encloses the torque sensor and the drive mechanism and is separate from a steering gear. The drive housing also has a mounting feature to which a housing of the motor is fixed. The drive housing also has a first bearing and a second bearing rotatably supporting the actuator shaft in the drive housing.
