Question: The closest I was able to find is ***in Kürze***.

Is there a translation that means something similar as it does in English?

Answer: 
**In Kurzform.**

This is in my opinion the best translation. Google hits like [*Unsere Forderungen in Kurzform*](https://artenvielfalt-brandenburg.de/wp-content/uploads/2019/04/Infoblatt-2_Forderungen-in-Kurzform.pdf) or Bad Kissingens [*Geschichte in Kurzform*](https://www.badkissingen.de/stadt/geschichtliches/geschichten-und-legenden/35896.Geschichte-in-Kurzform.html) are perfect examples for which the idiomatic translation is "in a nutshell" ("our demands in a nutshell", "the city's history in a nutshell").

Other suggestions: Leo [has an entry](http://dict.leo.org/ende/index_de.html#/search=in%20a%20nutshell&searchLoc=0&resultOrder=basic&multiwordShowSingle=on) for "in a nutshell". In addition to the other suggestions they propose 

* *zusammenfassend* (to sum up): this is a good neutral translation which at least hints a bit at the "essence" quality of "nutshell";
* *kurz und bündig;*
* for "to put in a nutshell": *auf den Punkt bringen.*

I like the last one because it emphasizes that what's said is not just short but focused ("auf den Punkt").
The Latin "in nuce" is sometimes used in German, but it's a lot more highbrow than "in a nutshell".
