Yes, the constant in that formula is the torque required per radian of angular deflection. The modulus I referred to was yet another torsional constant. Apologies.
The point I should have made, though, in answer to the original question, is that you won't find this particular constant in any tables. It is dependant on the actual length of the torsion wire, and possibly other factors, as well as the material from which it is made. It's like the spring constant for a spring. You don't find it's value in a table, but rather measure it experimentally. It depends on a number of factors and is unique to that wire.
What you will find in tables is the modulus of rigidity for various materials. This is the property, specific to the material, that will affect the period of the pendulum.
