S-76 collective/yaw coupling

Help please

Trying to understand the collective / yaw couple in the S76 mixing unit and I have emerged confused. With the anti-clockwise direction of the main rotor the fuselage would, with increased torque, want to turn right with increase in collective pitch, and vice versa. So why in the mixing unit will collective increase with right pedal input? My small brain seems to only understand that with an increase in collective, the nose will swing right, therefore requiring left pedal input to compensate. I apologise for my limited brain power and lack of understanding on this mechanical matter, and an explanation to drag me from the depths of ignorance would be very much appreciated.

Kind regards
