We see from your search that you're looking for information on the term "Torsional Stiffness",
and we have a large number of manufacturers' news releases and technical articles here on Engineeringtalk which will be of interest.
Let me be your guide.
Start with
the news release Shaft coupling transmits torque without side loads from
Schmidt-Kupplung, which we summarised at the time by saying "The all-metal coupling is designed to transmit high torque in a compact envelope and provides high torsional stiffness".
A couple of weeks before,
we featured the news release Online program eases coupling choices from
Zero-Max: "To select the right CD coupling, the system designer simply enters the coupling size or max torque capacity and the two bore sizes".
In November 2007, we covered the news from Schmidt-Kupplung
concerning its Semiflex Compact Plus C 230
- take a look at Compact coupling enables precision conveying
which says: "The Semiflex Compact Plus C 230 provides a combination of high torsional stiffness, a very short design and a high radial misalignment capacity".
Take a look also at the news release from Reliance Precision Mechatronics, Linear motion assembly handles high speed,
as well as Couplings provide high torsional stiffness from Zero-Max,
and Couplings transmit high rev/min from Ondrives/Rino Industries.
