Calling all B737NG/B757 mechs and crew...

I was looking at adding a mechanism to the crossover tube to simulate the 5 lb breakout from centered for the elevators.  (Yes, Jenny, there is an actual center...)

Please see attached. 

You cannot view this attachment.

Is this breakout mechanism in the schematic to allow one end of the torque tube to disengage from the other end in case of a jam?

Otherwise, what's the purpose?

Thanks.
