The torque I quoted is for 12.9 grade bolts- your lower value is probably for 10 grade or so. FWIW the factory bolts are 12.9 grade. The yokes are quite tough and my replacement bolts have a couple threads out beyond the yoke, so I had no fear torquing them to bolt spec (from memory, obviously I'm a little high at 46nm) 
What is the actual MG service spec for the yoke bolt torque?

The Workshop Manual does not specify a torque for the driveshaft pinch bolts, beyond that listed in the basic table for bolt sizes. It does refer to the fasteners holding the shaft to the gearbox as "high resistance screws ."

I do know for sure you want to tighten the bolts equally and together.
