Modular anti-rotation drilling systems and methods actuated by fluid pressure

A method for axially aligning a drillstring in a well borehole having a borehole surface, comprising:

• adding to a drillstring above the drilling motor a device that deploys tools against the borehole surface at an axial location where the device is axially located within the borehole;
• disposing the drillstring into the borehole;
• applying fluid pressure from a fluid to the device to deploy the tools against the borehole surface at the axial location;
• wherein the device comprises:
• an upper mount fixture and a lower mount fixture disposed opposite thereof and in axial alignment therewith, the upper mount fixture slidably disposed within a housing, wherein the upper mount fixture is driven towards the lower mount fixture by a fluid applying a fluid pressure, the fluid passing through an upper mount fixture passageway, the lower mount fixture positioned within the housing and fixed to the housing so as to not allow for slidable movement within the drillstring;
• the upper mount fixture and the lower mount fixture connected by at least two yoke assemblies;
• each yoke assembly comprising an upper yoke and lower yoke to form an articulated joint;
• and
• the tool connected to a first end of the upper and lower yokes;
• wherein upon moving the upper mount fixture towards the lower mount fixture, the articulated joint moves radially way from the central axis of the housing.
