Yep, I'll third that - it won't make a difference.
It's all about the moment around the pivot point, so if the adaptor runs at a right angle through the centre of pivot in the torque wrench then no adjustment is necessary.
Maybe Shazzam will be along to explain the physics of it.... personally I've just finished work and my brain is already fried for the day!
