Abstract: A flange connection set includes a modified compact flange, having a channel for external-internal seal tests, coupled to a connecting component, and coupled between the compact flange and the connecting component, there is a KX sealing ring with a radius closer to the radius of the conduit. Different types of keys provide the flange connection the ability to withstand high shear and torsional loads without affecting its operation, while also resisting high bending moment loads and preserving the integrity of the sealing ring and the fasteners.

Abstract: A torque sensing system is provided in a coupling connecting a drive and driven shaft by tension members that transmit torque from one shaft to the other through tension in the tension members at least one of which is provided with a sensor to sense the tensile stress in one of the members and to provide a signal indicating the tension (torque) applied through the tension members. If desired, an axially extending column element may be positioned between the two shafts to absorb axial thrust of between the shafts and a second sensor sensing the stress in the column may be used to determine thrust substantially independent of torque. The system may be used to detect off-axis loads.
