The invention relates to an engine including an intake air flow control assembly. The intake air flow control assembly includes an actuator, a valve shaft, a first valve member and a drive member. The actuator includes a drive shaft defining a first rotational axis. The valve shaft defines a second rotational axis. The first valve member is fixed for rotation with the valve shaft and adjusts air flow from an intake manifold to an engine intake port. The drive member is engaged with the drive shaft and the valve shaft. The drive member extends around an outer circumference of the drive shaft and around an outer circumference of the valve shaft. The drive shaft is rotatable in first and second rotational directions opposite one another to rotate the valve shaft via the drive member and rotationally displace the first valve member.
