torsion bar system, i need help

* Then unscrew the bolt in the 3rd pic, this is your ride height/tension adjustment.

This is NOT a tension adjustment, only a ride height adjustment. You will NEVER add or remove twist to the bar as long as you have distance between the LCA bumper and frame. ALL the bolt does is move the body of the LCA away from the torsion bar socket arm (the piece the bolt rides against).
