Based on what I've seen, best thing would be the Torque Tool supports one of the protocols from https://www.ptc.com/en/store/kepware/drivers/torque-tool-ethernet . Specifically, this Kepware drivers allows an onsite Kepware server to retrieve data from the tool itself...then push it to wherever you want.
Of course, I would be very happy to then connect that Kepware to ThingWorx directly.
Regardless, I believe overall, from a time spent (=$), using KW as interface is the fastest way to do it.
I worked with this setup in two projects, and sometimes, if the overall response time (from after you press the enable button and when you receive data in ThingWorx) required modifying some timings.
Regarding these timings, my colleagues from Kepware's presales side have a lot of experience, and I advise to discuss with your Kepware sales representative or partner (to make the link with one of them).
