If so, is there e.g. a website or book were I can read a bit more about how it works in real organs?
Monophonic couplers are not an invention of Modartt; they already existed as a mechanical solution in traditional organ building.

"Melody and bass coupling
The melody coupling (also called the soprano coupling) is a technical invention from the time of pneumatic action. Instead of affecting all (pressed) keys, this only affects the top (highest) key and thus essentially filters out the highest note of a chord being played. Depending on how the melodic coupling works, this can now sound as desired, on a different work/manual or offset by an octave, or both. The bass coupling (also “pedal effect”) works analogously for the lowest key pressed; It is particularly suitable for players who are not yet familiar with pedal playing. Melody and bass couplings are found primarily in romantic organs with pneumatic action and are rarely built today. However, a bass coupler can be found in almost every digital sacred organ as a playing aid.
The organ builders van den Heuvel have also invented an alto coupler for St-Eustache (Paris) and the Copenhagen Concert Hall, which filters out the second highest key pressed. In combination with a soprano coupler, it makes it possible to sound a four-part set with different registrations for each voice without having to play with one hand on two manuals at the same time in a technically virtuoso manner."
