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.
hey it would cost approximately $80 000!
Today it would be $1500 for an elevator that would go 50 feet up. In 1800's it would cost $80.
Yes, you will need a certified professional and it will cost about $4000
Rotary screw compressors are used in many industrial compressed air systems due to the high volume they produce in comparison to reciprocating compressors. Rotary screws take up much less space, require no heavy flywheels, and need less maintenance than the recip. compressors. Oil free compressed air can be produced by large rotary screw compressors designed as such, while reciprocating compressors can do this only on a smaller scale due to the need for cylinder lubrication in the larger models.
estimation is how much you think it would costs and budget is how much you decide it will cost after several estimations. budget is how much you can spend.
Clarify
In 1858 it had not been invented, so the cost was zero.
Ford Escorts use an inline 4 cylinder overhead cam engine, not a rotary engine.
Mechanics in NZ who work on Rotaries are currently on holiday.
Rotary actuators average around $100 to replace. They are important because they move the read/write head to the proper data track.
$3,500 for the engine. Gaskets and Seals for a rebuildable block plus Labor Runs in the general area of $1300.00. Market research from Rotary Resurrection
How much is l8227/760313199 rotary watch worth
A white rotary sewing machine from the 1900s is worth about $130.
With couplings, 110 lbs

It varies, mostly depending on land acquisitions through eminent domain, because in the United States, the constitution requires just compensation for all land taken through eminent domain. Things like that can put the price tag in the million dollar range. Multi-lane rotaries would most likely cost more. For you non New Englanders, a rotary is New England speak for a traffic circle, or roundabout.
It would cost 300,568
