To protected pipe thread. Do not use as a pipe coupling. Thread don't taper and the wall is to thin and could crack.
Unfortunately, the answer to that question is difficult to come by without knowing the location and use of the rotary couplings. The answer could be anywhere from $200-$2000. Please specify use for rotary couplings.

couplings are used to join sections of long transmission shafts. couplings are also used to connect the shaft of a driving machine to the shaft of a separately built machine so as to give an effect of continuous shaft. the general classification of couplings is as given under: 1. rigid coupling 2. flexible coupling 3.Camlock coupling
What is the difference between rigid and flexible coupling.
Keys are used while joining two shafts using couplings. When the shaft rotates at speeds greater than what it is designed for, The key purposefully undergoes failure and thus prevents damage to both the shaft and the coupling.
knuckle threads are used in railway carriage couplings.
Rotary couplings is a mechanism used to move fluid that is under pressure from a static inlet to a rotating inlet. They can be bought at sites like DSTI and Amazon.
A coupling is a device used to connect two shafts together at their ends for the purpose of transmitting power. Couplings do not normally allow disconnection of shafts during operation.
Shaft couplings are used to couple or attach two shafts together, typically in an assembly where one shaft rotates and drives the other shaft -- for example, if a motor were to drive a pump, there would be a coupling between the two shafts. Shaft couplings can be rigid (accommodating no misalignment) or flexible (accommodating some angular and/or radial misalignment of the two shafts).

A coupling is a device used to connect two shafts together at their ends for the purpose of transmitting power. Couplings do not normally allow disconnection of shafts during operation, however there are torque limiting couplings which can slip or disconnect when some torque limit is exceeded.The primary purpose of couplings is to join two pieces of rotating equipment while permitting some degree of misalignment or end movement or both. By careful selection, installation and maintenance of couplings, substantial savings can be made in reduced maintenance costs and downtime.
A merchant account is an bank account used for transferring money, involving business transactions. For example, a merchant account can be linked with Paypal, which can be used on eBay for business.

A coupling is a gadget used to associate two shafts together at their closures to transmit control. Couplings don't ordinarily permit separation of shafts amid task, however there are torque restricting couplings which can slip or detach when some torque confine is surpassed.
In the US, this merchant code is used for electrical contractors. For example, an electrician.
