Interchangeable, debris insensitive and non-slipping reaction torque transfer system

An interchangeable actuation and reaction torque transfer system comprising:

• a. a torque transfer axis;
• b. an actuation socket comprising:
• i. a drive shaft torque interface on a first axial actuation socket end for coupling with a torque drive shaft;
• ii. an actuation interface on a second axial actuation socket end that is opposite said first axial actuation socket end for coupling with an actuation receiving structure;
• c. a reaction coupling comprising:
• i. a torque wrench interface on a first axial coupling end for coupling with a torque wrench housing;
• ii. a reaction socket interface on a second axial coupling end that is opposite said first axial coupling end;
• d. a reaction socket comprising:
• i. a coupling interface on a first axial reaction socket end for coupling with said reaction coupling;
• ii. a drain interface on a second axial reaction socket end that is opposite said first axial reaction socket end;
• e. a reaction washer comprising:
• i. a reaction washer axis;
• ii. a reaction torque receiving flange comprising a number of torque receive structures that are radially outward protruding and circumferentially arrayed around said washer axis along an outer circumference of said reaction washer for coupling with said drain interface;
• and
• iii. a conical bottom face comprising a number of bottom serrations that are circumferentially arrayed around said washer axis and that are radially inward extending from a circumference of said bottom conical face;
• such that only outward ends of said bottom serrations initially penetrate into a base surface followed by said bottom serrations gradually penetrating radially inward into said base surface towards said washer axis while:
• a. said reaction washer is placed in between said actuation receiving structure and said base surface with said reaction washer axis being substantially coincident with said torque transfer axis;
• b. said actuation socket is coupled with said torque wrench shaft and said actuation receiving structure;
• c. said reaction coupling is coupled with said torque wrench housing and said reaction socket;
• d. said reaction washer is coupled with said reaction coupling;
• e. an actuation torque is applied to said torque wrench drive shaft around said torque transfer axis;
• f. an oppositely acting reaction torque is applied to said torque wrench housing around said torque transfer axis;
• and
• g. said reaction washer is increasingly flattening out.
